Update Tracking Number

This method should be used to notify Trendyol of the package tracking number.

For Normal Order Packages:

• Package status should be Picking before using this service
• Use appropriate storeFrontCode for the region

For Rejected Return Packages (EUROPE & GULF):

• Use this same endpoint to update tracking numbers for rejected return packages
• The packageId refers to the rejected return package ID
• If tracking code already exists, you will receive error "Shipment tracking number cannot be updated"

Required:

• storeFrontCode as Header Parameter (to differentiate regions)
• cargoSenderNumber and providerCode in request body
• returnTrackingNumber is optional (for Germany only)
